I’m not sure whether or not I blogged about this before, but here it is just for me to actually remember what, in which order I need to do. If you got the list in form of a csv file, simply do the following:

1
2
3
4

wget -q http://tinyurl.com/4atkz7 -O - | grep "(" | cut -d'(' -f2 | cut -d')' -f1 | awk '{ print tolower($1) }' > retirements
for developer in $( < retirements ); do
   retire.py --metadata $developer /cvs/gentoo-x86/ | diffstat > ~/metadata.$developer
done

That’ll give you a detailed list of which metadata.xml need to be changed.
